A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago. Its analysis of minerals in southern China indicate that volcano ...

Let’s Talk About the 1,800-Plus 'Young' Volcanoes in the US Southwest

They're born. They live once, erupting for a period that might last for days, years or decades. Then, they go dark and die. This narrative describes the life of a monogenetic volcano, a type of ...

The Silent Build-Up to a Super-Eruption

It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake ...

How to Better Identify Dangerous Volcanoes

The more water is dissolved in the magma, the greater the risk that a volcano will explode. A new study now shows that this simple rule is only partially true. Paradoxically, high water content ...

What Lies Beneath: Volcanic Secrets Revealed

Lava samples have revealed a new truth about the geological make-up of the Earth's crust and could have implications for volcanic eruption early warning systems, a new study has ...

Threat of Catastrophic Supervolcano Eruptions Is Ever-Present

Scientists have studied an ancient supervolcano in Indonesia and found such volcanoes remain active and hazardous for thousands of years after a super-eruption, prompting the need for a rethink of ...

Climate Change Will Transform Cooling Effects of Volcanic Eruptions

Researchers have shown that human-caused climate change will have important consequences for how volcanic gases interact with the ...

Minor Volcanic Eruptions Could ‘cascade’ Into Global Catastrophe

Researchers call for a shift in focus away from risks of 'super-volcanic' eruptions and towards likelier scenarios of smaller eruptions in key global 'pinch points' creating ...

Sea Levels Influence Eruptions on Volcanic Island

The rise and fall of sea levels influence the likelihood of volcanic eruptions on the Greek island of Santorini, new research has discovered. Analyzing the timings of eruptions over hundreds of ...

Giant Friction Experiment at Kilauea Volcano

A new analysis of the 2018 collapse of Kilauea volcano's caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the ...

Huge Volcanic Eruption Disrupted Climate but Not Human Evolution

A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, ...
